Energy Levels and Transitions in ⁷¹As from (p, γ) Reaction on ⁷⁰Ge

Abstract

The ⁷⁰Ge(p, γ)⁷¹As reaction has been investigated in the energy range from E_p=1.0 to 2.5 MeV. Excitation function was obtained for the reaction over this energy region. High-resolution measurements of the de-excitation γ-rays from this reactions have been made at E_p=2.434 and 2.030 MeV by using a 50 cm³ Ge(Li) detector. The energy levels of ⁷¹As up to 2947 keV excitation and γ-ray branching ratios were determined; several new levels are proposed. The Q value for this reaction was also determined.
